How to control update of item attributes by responsibility in 12.2.5 ?

Different groups here are responsible for various inventory item attributes.  Engineering may determine the technical details, which Purchasing shouldn't change.  While at the same time, Purchasing determines the lead time, minimum purchase quantity, sourcing, etc, and Engineering shouldn't change those.  We want to allow a user to update only specific item attributes based on his responsibility.  This could be done with personalizations in the older-style forms but can it be done with the new forms?   If you can provide an overview of how it could be done, it would be greatly appreciated.
